WATER-HEATER.

Beit known that l, WILLIAM G. TAYLOR, oi Pittsburg, Allegheny county,Pennsylvania, have invented a new and useful Water-Heater,

5 of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is a side elevation, partly broken IOaway, showing the preferred form of my heater; and Fig. 2 is a partialcross-section of the same with the tank omitted.

My invention relates to the class of waterheaters wherein the gas-How tothe burner is controlled either by thermostatic or other automatic meansand is designed to provide a simple and effective device or' thischaracter in which the water will be rapidly and economically heated.

2O The invention is designed to do away with the coil system, which isexpensive and liable to get out of order, and to make a cheaper and moreefficient construction.

In the drawings, Qrepresents a reservoiror domestic boiler from the topof which leads the house-pipe 3 to `the house system. This pipe ispreferably' provided with a controlvalve 1, which is closed when theheater is being cleaned out. The cold-water pipe 5 is shown as leadingto the upper end of a waterbarrel 6, con taining' a thermostatic device,this barrel connecting to the reservoir through the bottom pipe 7. Thethermostatic device is connected to a gas-valve located in thevalvecasing 8, which is placed in the gas-supply pipe 9, leading down tothe lower mixer 10. From the other end of the pipe 9, at the top, leadsthe pilot-light gas-supply pipe 11, which leads to the small mixer l2,supplying the 4v pilot-light burner 13, which is located centrallybeneath the central header 14. This header is connected centrally by apipe 15, leading into the center of the bottom head 16 of the boiler,and from the header lead the radial tubes or pipes 17, which areconnected at their outer ends to vertical pipes 18 by Ts 19. Each'T 19contains a removable screwplug 20, which may be removed for cleaning.

It will be noticed by looking at Fig. 2 that the radial pipes arearranged so that two of them are always in line with each other, thusenabling a cleaner to be run through the length .of two of the tubes toclean out scale or other deposits.

The vertical pipes 18 lead to an annular 55 'tube 2l, surrounding theintermediate portion of the reservolr, and from which two pipes 22 leadupwardly and into the sides of the boiler above the pipe 7,- leadingfrom the waterbarrel. 6o

The hand-valve 23 controls the gas-supply for both burners, while thelower valve 24 controls the supply to the pilot-light burner.

The main burner consists ot' a hollow body portion 25, having a seriesof radial burner extensions 26 extending' beneath and in line with theradial pipes 17. These burner extensions 26 are closed at their outerend with the exception of one into which projects the pipe 27, leadingfrom the mixer 10. The pilot-light supply-pipe and burner extendcentrally through the hollow body ot' the main burner and areindependent of it.

In the operation of the device the cold water Hows in through thewater-barrel and entering the boiler or reservoir sinks to the bottomthrough the warmer water therein. It then passes out through the bottompipe, through the lower header and the pipes 17 and 18, into the ring21. As the water flows through the 8O header and pipes 17 it is heatedby the pilotlight and by the main burner at such times as the gas issupplied thereto. Then a cock is opened in the house system, the `flowof water through the cock passes through a conduit of 8 5 much smallerarea than the combined areas of the vertical pipes 18. The ow throughthese pipes is therefore comparatively slow, thus insuring a rapidheating of the water in the header and radial pipes. The water enteringthe pipe 21 passes up through the vertical pipes 22 and into the upperportion of the heater.

In order to wash out the heater, I preferably provide one of the Tconnections 19 with 95 a valved extension 28, as shown in Fig. 2.

By closing the valve 4 and opening the valve in pipe 28 the water willHow out and wash out the pipes. I preferably inclose the heating-pipesby a surrounding casing 29, which may be of metal lined with asbestos orother suitable material. This casing preferably incloses the lower partot the heater and is contracted or extended inwardly to the reservoir orboiler part above pipe 21. rIhis casing may be provided at one side withan olitakeiiue in the usual manner. The heated gases are thus retainedin contact with the pipes 18 and the ring 2l as they rise around theheaterbody.

The advantages of my invention result from the peculiar arrangement ofcirculating-pipes in connection with the domestic boiler. The water isthus heated rapidly and economically without the use oi' expensive coilsystems, and the pipes may be rapidly and easily cleaned.

Variations may be made in the form and arrangement of the heater and itsvarious parts Without departing from my invention.

I claim l. A heater having a central reservoir, a water-supply pipeleading into said reservoir, a pipe connection leading down from itslower head to a separate central header, and a hollow ring surroundingthe boiler and having pipes leading down to the header, said ring havingconnections leading into the boiler; substantially as described.

2. A heater having acentral reservoir, awater-supply pipe leading intosaid reservoir, a pipe extending horizontally around at least a I partof an intermediate part of the reservoir 3. Aheater havingacentralreservoir, a water-supply pipe leading into said reservoir, a hot-waterpipe leading from its top, a pipe leading from its bottom down to aseparate central header, pipes leading from said header up to a ringextending around'an intermediate part of the boiler, a pipe connectionfrom said ring into the boiler and a burner beneath the header;substantially as described.

4f. In a heater, aboiler having pipe connection to a central lowerheader, pipes leading outwardly and radially from said header andupwardly to a ring extending at least partially around an intermediateportion of the boiler, and removable cleaning-plugs in the ends of theradial pipes; substantially as described.

5. In a heater a reservoir or boiler havinga hot-water outlet at itstop, a cold-water inlet leading into its intermediate portion, a hollowring extending at least partially around the boiler and having depending.pipes connected to a central lower header, a connection between theheader and lower part ofthe boiler', and pipes leading from the ringinto the boiler; substantially as described.

6. A header having a central reservoir, a cold-water pipe leading to athermostatic barrel connected to the reservoir, a header below thereservoir and connected thereto, radial pipes leading from the headerand connected to a ring extending at least partially around the boiler,pipes leading from said ring into the boiler, a burner below the headerand a gas-supply to the burner having a valve connected to thethermostatic device; substantially as described.

In testimony whereof I have hereunto set my hand.
